The wound protector has an annularly collapsible proximal ring and a flexible sleeve extends between the proximal ring and distal ring. After positioning of the distal ring in a wound, the proximal ring is expanded to draw the sleeve taut between the rings and is drawn tight against the wound. In one embodiment, the proximal ring includes a bent hollow tube with an arcuate rod in the tube bridging the open ends of the tube and a compression spring extending within the tube against the ends of the rod to bias the proximal ring into an extended state. Finger grips on the ends of the tube allow for squeezing of the tube into a collapsed state.

Wound protector

The wound protector has an annularly collapsible distal ring, an expansion member and a flexible sleeve extending between the distal ring and expansion member. After positioning of the distal ring in a wound, movement of the expansion member into an extended state expands the sleeve while drawing the sleeve tight against the wound and the expansion member against the patient.

In one embodiment, the wound protector has an annularly collapsible proximal ring and a flexible sleeve extends between the proximal ring and distal ring. After positioning of the distal ring in a wound, the proximal ring is expanded to draw the sleeve taut between the ringsand is drawn tight against the wound. In a second embodiment, the wound protector has a flexible sleeve secured between a distal ring and proximal ring of fixed diameters. In addition, an expansion member is disposed within a loop of the flexible sleeve about the proximal ring. After positioning of the distal ring in a wound, movement of the expansion member into an extended diametric state expands the loop in the sleeve diametrically while drawing the rings towards each other.
